Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment for the ends of large-diameter rollers, and particularly relates to a welding device for the ends of large rollers. Background Technology

[0002] In the field of material conveying roller technology, rollers used for conveying heavy materials are currently all large rollers. These rollers consist of a roller body, end caps, and a drive shaft. Currently, most of these rollers are formed by manual welding. This is because the roller diameter is 40-60 cm and the length is more than 1.5 meters. When the roller is placed horizontally, the personnel need to squat down to weld. When the roller is placed vertically, the personnel need to raise their arms to weld. Neither method is suitable for manual operation, and the welding process has become a bottleneck process in this industry.

[0003] Those skilled in the art have attempted to use automated equipment for welding, but such large rollers are not common components in the industry. There are few machines for welding such large rollers and the manufacturing cost is high. During the welding process, the welding end needs to rotate around the roller. This rotation causes the welding head to be unstable and the welding quality is difficult to control.

[0004] Regarding the aforementioned technical problems, the urgent technical problem to be solved by those skilled in the art is: how to design a simple equipment or device that can adapt to the welding of such large rotating parts through technological improvements, which can achieve stable welding of the roller ends, is easy to operate, and will not bring high cost investment to the production enterprise in terms of equipment costs. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, this utility model proposes a large roller end welding device, which supports the roller body to rotate by setting a roller drive unit and achieves positioning during rotation. Welding can be achieved by simply adjusting the position of the welding end. The existing technology replaces the movement of the welding gun with the movement of the roller body, effectively avoiding the instability caused by frequent adjustment of the welding gun.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A large roller end welding device includes an inclined machine platform with several support bases on the platform. The support bases include a driving support base and a driven support base. Both the driving and driven support bases are equipped with a base drive screw and a bottom drive handwheel. Two threaded blocks and two support plates are symmetrically arranged in conjunction with the base drive screw. The base drive screw has two symmetrically arranged threaded sections with opposite rotation directions. Drive wheels are fixed to the two support plates of the driving support base, and driven wheels are fixed to the two support plates of the driven support base. The drive wheels are connected to a drive motor for operation. The inclined machine platform is equipped with a positioning frame at its lower end, and the positioning frame is equipped with a positioning cone to support and position the roller mandrel. The inclined machine platform is equipped with a welding frame at its high end. The welding frame is equipped with a vertical adjustment rod. A horizontal beam is fixed on the vertical adjustment rod. A welding drag rod is fixed on the horizontal beam by a positioning frame. A welding gun holder is installed on the welding drag rod.

[0007] A flue rod is fixed to the transverse beam by a positioning frame, and a flue bracket is provided on the flue rod. The flue bracket enables negative pressure suction of the smoke and dust extraction device.

[0008] The positioning frame is equipped with an adjusting sleeve, which has a locking positioning hole. The welding rod or flue rod passes through the adjusting sleeve and can achieve positioning and locking. This structure allows for fine-tuning of the welding torch and flue after installation, and the fine-tuning of the welding rod in particular can effectively control the welding accuracy.

[0009] The welding frame is provided with guide seats on the left and right sides, and a light shield is provided in conjunction with the guide seats. The light shield can effectively block the strong light and welding chips generated during the welding process.

[0010] The inclined machine platform is equipped with a bottom support frame at its lower end. An axial adjustment chamber is provided on the bottom support frame. The axial adjustment chamber is equipped with a sliding groove and an axial screw. A positioning frame base is provided in the sliding groove. The positioning frame base is connected to the axial screw through a screw nut. The positioning frame is vertically arranged and has a vertical groove on the side facing the roller. A vertical screw is provided inside the positioning frame. The vertical screw drives the vertical screw nut to move. A positioning cone is fixed on the vertical screw nut.

[0011] The inclined machine platform is equipped with a high-leg support base and a low-leg support base at its bottom, which together provide support for the inclined machine platform.

[0012] This invention has the following advantages: By setting a drive support base and a driven support base on an inclined machine platform, both the drive and driven support bases are equipped with a base drive screw and a bottom drive handwheel. Two threaded blocks and two support plates are symmetrically arranged in conjunction with the base drive screw. Drive wheels are fixed to the two support plates of the drive support base, and driven wheels are fixed to the two support plates of the driven support base. The drive and driven wheels together support the roller. This invention also achieves low-end positioning through a positioning frame and positioning cone at the lower end of the inclined machine platform. A vertical adjustment rod and a transverse beam are set at the upper end of the inclined machine platform. A welding drag rod is fixed to the transverse beam via a positioning frame, and a welding torch holder is mounted on the welding drag rod. During operation, the welding torch remains stationary while the roller body rotates, achieving end welding. The controllable automatic rotation via the drive wheel effectively improves welding efficiency and accuracy. This invention has a simple structural design, is easy to operate, and has low overall operating costs, reducing the configuration costs for users. It is an ideal large roller end welding device.

[0015] The large roller end welding device disclosed in this utility model has a novel and reasonable structure, but the benefits of its improved overall structure are obvious. In order to make the improved effect of this utility model clearer, the following describes this utility model in further detail through specific embodiments.

[0016] Example 1: A large roller end welding device, as shown in the attached figure, includes an inclined platform 1. The inclined platform 1 consists of multiple high-leg support seats 11 and multiple low-leg support seats 12. The inclined platform 1 is tilted by the cooperation of the multiple high-leg support seats 11 and multiple low-leg support seats 12. After the roller 9 is installed in this structure, it has its own downward gravity. When axial support is achieved at the bottom, there is no need to set up a positioning or fixing device in the axial direction. It can be rotated by steering driving force.

[0017] The inclined machine base 1 is provided with several support bases. In this embodiment, the several support bases include a driving support base 2 and a driven support base 3. It should be noted that the internal structure of the driving support base 2 and the driven support base 3 is the same, and they are used to support the driving wheel 24 and the driven wheel 33, respectively. In more detail, both the driving support base 2 and the driven support base 3 are provided with a base driving screw 32 and a bottom driving handwheel 31. Two threaded blocks (not standard) and two support plates 20 are symmetrically arranged in conjunction with the base driving screw 32. The base driving screw 32 has two symmetrically arranged threaded segments with opposite directions of rotation. The purpose of this arrangement is that when the bottom driving handwheel 31 is suspended at one end, the gap between the two driving wheels 24 or the two driven wheels 33 can be adjusted, thereby facilitating welding with different diameters of 9.

[0018] The drive wheel 24 is fixed to the two support plates 20 of the drive support base 2 by bearing brackets 23, and the driven wheel 33 is fixed to the two support plates 20 of the driven support base 3. The drive wheel 24 is connected to the drive motor 21 through the gearbox assembly 22 to achieve drive.

[0019] The inclined machine platform 1 has a bottom support frame 4 at its lower end. The bottom support frame 4 adopts a Z-shaped structure, which can improve the stability when positioning the roller 9. A support plate 41 is provided on the top surface of the bottom support frame 4, which fixes the axial adjustment chamber 5. The axial adjustment chamber 5 is provided with a sliding groove 51 and an axial screw 52. An axial adjustment handwheel 53 is provided at the end of the axial screw 52. A positioning frame base 61 is provided in the sliding groove 51. The positioning frame base 61 is connected to the axial screw 52 through a screw nut. A positioning frame 6 is vertically provided on the positioning frame base 61. Figure 2 As shown, a vertical groove is provided on the side facing the roller 9. A vertical lead screw 63 is provided inside the positioning frame 6. A vertical axial adjustment handwheel 64 is provided at the top of the vertical lead screw 63. The vertical lead screw 63 drives the vertical lead screw nut 65 to move. A positioning cone base 66 is fixed on the vertical lead screw nut 65. The positioning cone base 66 and the positioning cone 67 are integrally set. With this structure, the entire axial adjustment chamber 5 is set at the lower end of the inclined machine table 1. Through the cooperation of the axial lead screw 52 and the vertical lead screw 63, the position of the positioning cone 67 can be adjusted. When the roller 9 is placed, the positioning cone 67 is supported and positioned on the drive shaft 91.

[0020] The inclined machine platform 1 is equipped with a welding frame 8 at its high end. The welding frame 8 is a U-shaped or Z-shaped frame. Two adjustment slots 81 are provided at the top of the welding frame 8, which are used to vertically lock and fix the vertical adjustment rod 82. Two rows of adjustment holes 83 are vertically provided on the vertical adjustment rod 82, which are used to lock and fix the transverse beam 84. A welding drag rod 87 is fixed to the transverse beam 84 by a positioning bracket 85. An angle adjustment seat 871 is provided on the welding drag rod 87, and a welding torch bracket 872 is provided on the angle adjustment seat 871 to fix the welding torch. The angle adjustment seat 871 can be locked with bolts, allowing adjustment of the welding angle of the welding torch. The purpose is to adjust the relative position of the welding torch and the welding point 92, thereby improving welding accuracy.

[0021] Furthermore, a flue rod 88 is fixed on the transverse beam 84 by a positioning frame 85, and a flue bracket 89 is provided on the flue rod 88. The flue bracket 890 can be used to install the flue pipe and the flue suction device to achieve negative pressure suction.

[0022] Furthermore, the positioning frame 85 is provided with an adjusting sleeve 86, which has a locking positioning hole. The welding drag rod 87 or the flue drag rod 88 passes through the adjusting sleeve 86 and can achieve positioning and locking. This structure allows for fine-tuning after the welding torch and flue are installed, and the fine-tuning of the welding drag rod 87 in particular can effectively control the welding accuracy.

[0023] The welding frame 8 is provided with a guide seat 71 on at least one side of its left and right sides, and a light shield 7 is provided in conjunction with the guide seat 71. The light shield 7 can effectively block the strong light and welding chips generated during the welding process, ensuring the safety of the surrounding workers.

[0024] In operation, the pre-welded roller 9 is placed onto the drive wheel 24 and driven wheel 33 by an overhead crane. During this process, the gap between the drive wheel 24 and driven wheel 33 can be adjusted via the bottom drive handwheel 31 to accommodate rollers 9 of different diameters. After adjustment, the vertical screw 63 inside the positioning frame 6 is adjusted. The vertical screw nut drives the positioning cone 67 to move vertically, thereby providing compression support at the axis of the drive shaft 91. With this structure, after the roller 9 is placed, the positioning cone 67 rests on the drive shaft 91 to achieve axial support and positioning. Then, the welding torch position and the negative pressure flue suction position are adjusted to accurately achieve welding and negative pressure suction. In the design of the negative pressure flue, negative pressure flues can be set on both sides of the welding torch to achieve efficient smoke exhaust.

[0025] During the welding process of this utility model, the welding torch remains stationary while the roller 9 rotates to achieve end welding. It achieves controllable automatic rotation through the drive wheel 24, which effectively improves welding efficiency and accuracy. This utility model has a simple structural design, is easy to operate, and has low overall operating costs, which can reduce the configuration costs of the user unit. It is an ideal large roller end welding device.
